Lightning Grounding | lightning-protection-institute

2. Introduction to Lightning Protection Institute The world’s best and most critical expertise for the proper implementation of IEEE Standard 1692; which is a treatise for multi-purpose communications and high-voltage installations. We have found from forty one (41) years of experience, and special expertise, that it’s far too easy to "get it wrong" in cookie-cutter applications of the tried-and-true requirements of Standard 1692, leaving expensive equipment vulnerable to costly damage and weeks off line for extensive repair.

5. We've all heard the saying that lightning never strikes the same place twice, but is it true? The answer is absolutely not. In fact, lightning occurs so frequently that it would be hard for that to be true. At any given time, there are 2000 thunderstorms on the planet, and they produce around 6000 lightning strikes every minute. That's more than 8.5 million strikes a day. They each have 100,000 times the power of household electricity. The most important aspect in the application of Standard 1692 is that the final protection package design has to be perfectly correct in every aspect to provide failure-proof protection. One small error in proper application can make a protection design package totally useless.

6. Lightning Protection and Grounding Facts and Fallacies The idea of preventing a lightning strike goes back to 1754 when the master himself, Ben Franklin, was still experimenting. Prokop Divisch installed 216 earthed points on a 7.4 meter wooden frame, and a few years later it was suggested by Lichtenberg that a catenary of barbed wire over a house could prevent a strike. The idea of using multiple points to discharging a cloud and neutralize its charge has been thought about and tried for years. "The idea is just as bogus now as it was then." -- clarification added by LPGI. It may be a bit technical but read on to understand why.

Formal presentation, seminars, depositions and testifying, either court proceedings or mediation and arbitration: $375/hr. including travel portal to portal.

8. Recommended Guide For The Protection Of Equipment Workable special protection methods to prevent lightning damage to equipment and possible harm to associated working personnel are presented. This document covers: protection methods for Ground Potential Rise (GPR), isolation, shielding, and grounding from lightning. Warning: Protecting a structure from lightning does absolutely nothing to protect the equipment within that structure, and the housed equipment is normally worth many times the value of the structure.

9. LPGI Lightning and Grounding Course {This is the only training available in the country which provides methods for grounding and protecting tower and equipment building from lightning induced Ground Potential Rise (GPR)} This is also the only training in the country that covers IEEE Standard 1612-2011, the only national lightning equipment standard. This two (2) day training seminar will be suit-cased to your location for $1,000 per attendee with a minimum of ten (10) attendees plus instructor travel expenses, and $150 per course manual.
